Screen resolution checker
On a high-density screen, 100 percent in the browser is not one image pixel per screen pixel. These numbers tell you what you are really looking at.
Why a seller should care
Marketplace zoom shows your image at its real pixels. If your laptop has a pixel ratio of 2, a 1000 px image displayed at 1000 CSS pixels is being upscaled to 2000 physical pixels, so it looks softer on your screen than the file really is. Equally, a slightly soft image can look acceptable on a phone and poor on a desktop zoom.
| Pixel ratio | To see true 100% |
|---|---|
| 1 | View at 100% |
| 1.5 | View at about 67% |
| 2 | View at 50% |
| 3 | View at about 33% |
